380 bhp no probs from a t34.48 lol

I ran mine at 36psi and held it flat out to the limiter, the wastegate could have been welded shut once the spike had been controlled, and it made 370 bhp 420lb/ft
so I wouldn't say it's no problem, more like impossible as they simply run out of puff top end.
Good for torque and punch but no good for ultimate bhp.

T34.63 will do 380 bhp.

For the record I have a graph from my t34.48 showing 470 bhp, I guess it depends what you believe lol.
